In order to obtain versatile ulitity of host molecules, three new chiral calix [4] crown ethers containing aza, thio atoms bearing two chiral sites provided by -cysteine ester were synthesized by the condensation of calix [4] arene diacid dichloride with oligoethylene glycol bridged bis-amino acid methyl ester. All new compounds were characterized by NMR, MS and elemental analysis.

以-半胱氨酸为手性源，利用多甘醇二氯醚在碱性条件下对半胱氨酸巯基进行烷基化反应，成功地合成了多甘醇醚链桥联的半胱氨酸衍生物，醚化反应后，在高度稀释条件下与对叔丁基杯[4]芳烃二乙酰氯进行双功能基缩合反应成功地合成了新型的手性杯[4]含氮、硫杂冠醚，并利用〓H NMR、MS等谱图手段对其结构进行了表征。

The thesis is right to draw in machinery , push away and depend on , clamp, three devices of structure and function have made a throughgoing and painstaking analysis, has calculated and checked relevant structure; Have chosen some components in hydraulic pressure, has drawn the principle picture of the hydraulic pressure, and has made brief illustration to its movement course; Go up and down with the programming realization of PLC in the electric respect, draw , push away and depend on, clamp movement circulation.

Research content and research object. The Coagulant Dosage Automatic Control System is discussed emphatically. Including the relation is put up between target standard and the infection factor by date analyzed chart and educational established and sum up the best working point. The target standard including SS COD and OIL .The infection factor including the dosage of PAC PH Mill INTENSION and TIME. On the basis of craft character and control request, it makes a selection of scheme to the whole control system. Finally a scheme is chosen and described as follows: CPU222 of SIEMENS PLC S7-200 is used as the control kernel. V606IC TOUCHER is used as communication man and machine. Controlling pump, compressor, metric pump of system by gathering andanalyzing the flow, PH of raw water .
